Precautions for Correct Use

Operating Environment
• This switch is only for indoor use. If it is used in outdoor, it may cause switch failure.
• Take special care if products are to be used at places where there is fine powder, mud and/or foreign materials accumulating. Check actual using conditions before using. If this is unavoidable, highly recommend integrating protective equipment. This is considered not Moujen’s obligations.
• Seal material may deteriorate if a Switch is used outdoor or where subject to special cutting oils, solvents, or chemicals. Always appraise performance under actual application conditions and set suitable maintenance and replacement periods. This is considered not Moujen’s obligations.
• Install Switches where they will not be directly subject to cutting chips, dust, or dirt. The Actuator and Switch must also be protected from the accumulation of cutting chips or sludge.

Handling & Usage
• Do not remove or replace any built-in switches. Doing so may damage the product, resulting in increased risk of malfunctioning.
• Do not use excessive force to insert, remove or twist keys of key-selector products. Doing so may damage the product, resulting in increased risk of malfunctioning.
• To change the installation position of the actuator: By loosening the Allen-head bolt on the actuator lever, the position of the actuator can be set anywhere within 360°.
• To change the orientation of the head: By removing the head screws (two or four screws), mounting in any of four orientations is possible. Be sure to change the plunger for internal operations at the same time. The roller plunger can be set in either of two positions at 90°.
• Flipping the roller to a different side: Loosen the Allen-head bolt, allows flipping the roller to the opposite side.
• Adjusting the length of the rod or lever: The length of the rod or lever can be adjusted by loosening the Allen-head bolt.
• Adjusting the rolling arm lever: (i) The roller arm can be set freely within a range of 225° after loosening the nut. (ii) The roller arm mounting bracket can be set in any direction after loosening the nut.

 Mounting and Tightening
• Please view each individual product page’s allowed parameters for details.
• Please follow these parameters diligently. Otherwise products may not function properly.

Wiring & Cabling
• Use M3.5-nylon insulation covered crimp terminals (round type)
• Appropriate wire size is AWG18.
• Do not supply electric power when wiring. Otherwise electric shock may result.
• Do not pull on the wires with excessive force.
• Avoid connecting the wires directly to the terminal. Instead, attach using a crimp terminal.
• Grounding is only installed on models with ground terminals.
• In the case of prewired connector and direct connector: Holding the connector certainly when pulling connector. Do not pull the cable with excessive force.

Conduit Installation
• The connector must be tightened at a suitable tightening torque. Tightening with excessive torque could damage the case.
• Select the connector based on the sealed rubber inner diameter for matching the cable outer diameter.
• When mounting the connector, use seal tape (not needed if the connector includes an O-ring) on the threaded section of the connector to ensure sealing performance.
• To ensure compliance of this Switch with the CSA standards, use of a waterproof connector compliant to CSA regulations.
• Using an inappropriate connector or assembling Switches incorrectly (assembly, tightening torque) can result in malfunction, leakage current, or fire. Be sure to read the connector instruction manual thoroughly beforehand.
• Even when the connector is assembled and set correctly, ends of the cable inside the Switch may come in contact. This can lead to malfunction, leakage current, or fire. Thus, be sure to protect the end of the cable from splashes of oil or water and corrosive gases.
• The following wiring is recommended for preventing the entry of fluids from the conduit opening.

Integrating into systems – Limit Switches
• Carefully determine the position and shape of the dog or cam so that the actuator will not
abruptly snap back, thus causing shock. In order to operate the Limit Switch at a comparatively
high speed, use a dog or cam that keeps the Limit Switch turned ON for a sufficient time so that
the relay or valve will be sufficiently energized.
• The method of operation, the shape of the cam or dog, the operating frequency, and the travel
after operation have a large influence on the durability and operating accuracy of the Limit Switch.
The cam or dog must be smooth in shape.

• Appropriate force must be imposed on the actuator by the cam or dog in both rotary operation
and linear operation. If the dog touches the lever as shown below, the operating position will not
be stable.

• Unbalanced force must not be imposed on the actuator. Otherwise, wear and tear on the actuator
may result.

• Mount so that the actuator travel after operation (OT) is not exceeded. If the travel after operation (OT) exceeds the limit, switch failure could result. When mounting the Limit Switch, be sure to adjust the Limit Switch carefully while considering the whole movement of the actuator.
• When using a pin-plunger actuator, make sure that the stroke of the actuator and the movement of the dog are located along a single straight line.
